The work of preparing International Standards is normally oarried out through ISO technical committees. Each member body Interested In a subject for which a technicat committee has been established has the right to be represented on that committee. Intemational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISOcoIIaborates closely with the Intemational Electrotechnical Commission (IEC) on aII matters of electrotechnìcal standardization. Internatìonfial Standards are drafted in accordance wlth the ruIes given in the ISOIiEC Directives, Part 2. The main task of technìcal committees is to preparo Intemationat Standards. Draft International Standards adopted by the technical committees are cìrculated to the member bodies for voting. Publication as an Intemational Standard requires approval by at Ieast 75 % 0t the member bodies casting a vote. Attention is drawn to the possibìlity that some of the etements of this document may be the subject of patent rights. ISO shall not be hetd responsìble for identifyìng any or aII such patent rights. . ISO 1183-1 was prepared by TechnicaI Committee ISOl’I'C 61, Plastics, Subcommittee SC 5, Physical- chemical properties. Together with the other parts (see below). this part of ISO 1183 cancels and replaces ISO 1183:1987, which has been technically revised.

This part of ISO1183 does not purport to address aII of the safety problems, if any, _associated with its use. It is the responsibility of the user of this part of ISO 1183 to establìsh appropriate health and safety practices and to determine the applicability of any regulatory Iimitations prior to use. 1 Scope This part of ISO 1183 specifies three methods for the determination 0t the density of non-cellular plastics in the form 0t void-free moulded or extruded objects, as well as powders, flakes and granules. — Method A: Immersion method. for solid plastics (except for powders) in void-free form. — Method B: Liquîd pyknometer method, for particles, powders, flakes, granules or small pieces of finished parts. i r— Method C: Titration method, for plastics in any volo-free form. NOTE Thìs part of ISO 1183 is applioable to pellets as Iong as they are void-free, Density is frequently used to follow variations in physical structure or composition of plastic materiale. Density may also be useful in assessing the uniformity of samples or specimens. Often the density of plastic materials wiII depend upon the choìce of specimen preparation method. When this is the case, precise details of the specimen preparation method wiII have to be included in the appropriate material specification. This note is applicable to aII three methods. 2 Normative references The following referenced documents are indìspensable for the application of this document.

At this point, add the more dense Iiquid in 0,1 ml amounts. Note the total amount of more -dense liquid added when the Iightest pieces of specimen become suspended within the Iiquid, at the Ievel to which they are brought by stirring, without moving up or down for at Ieast 1 min. At this point in the titration, note the amount of more dense Iiquid required. The density of the liquid mixture at this point corresponds to the lower Iimit of the density of the test specimen. Add more of the more dense liquid until the heaviest pieces of specimen remain ata constant Ievel within the Iiquid for at Ieast 1 min. Note the amount of more dense Iiquid required. For each pair of Iiquids, establish the relationship between the amount of more dense Iiquid added and the density of the resulting mixture, and plot the relationship in the form of a graph. ‘The density of the liquid mixture at each point on the graph can be determined by a pyknometer method. 6 Correction for buoyancy in air Where weighings are made in air, the yalues of the “apparent masses" obtained shaII be corrected to compensatefor the effect 0t the air buoyancy on the specimen and on any weights used.
